Answer:
4
Step-by-step explanation:
the equation for slope: (y2-y1)/(x2-x1)
the points are (1,0), and (3,8)
we can label them
x1=1
y1=0
x2=3
y2=8
now, substitute into the equation (m=slope)
m=(8-0)/(3-1)
m=8/2
m=4
I think 50 hope that's the answer
Answer:
42.5
Step-by-step explanation:
First find out what 1 unit equals on the second number line
34/4=8.5 so 1 unit = 8.5 dollars
the questions asks for 5 units so
8.5 * 5 = 42.5
<u>OR</u>
4/34=5/x
4x=34(5)
4x=170
x=42.5
Answer:
768
Step-by-step explanation:
Given that:
Error margin (E) = 5% = 0.05
Confidence level = 95%
Proportion p = 0.5 (since no prior value is given) ; also n1 = n2 = sample size
n = (Z / E)^2 * (1 - p)
1 - p = 1 - 0.5 = 0.5
Zscore at 95% confidence = 1.96
n = (1.96 / 0.05)^2 * 0.5
n = 39.2^2 * 0.5
n = 1536.64 * 0.5
n = 768.32
Hence, sample size = 768 SAMPLES
